Loch Rannoch is a large body of fresh water in Perth and Kinross, Scotland. Rannoch Moor is a large expanse of around 50 square miles of boggy moorland to the west of Loch Rannoch, in Perth and Kinross and Lochaber, Highland, partly northern Argyll and Bute, Scotland. Rannoch Moor is designated a National Heritage site.
It is notable for its wildlife, particularly famous for the sole British location for the Rannoch-rush, named after the moor.
